Abstract: Based on a lot of research experiments, this paper proposes the algorithm of orthogonal double axle solution for granulated objects, which has been put into practice and proved in the application of auto-separation system for watermelon seeds. This algorithm has the advantage of low time complexity and high precision compared with others. It can also be used in the solution of other similar granulated objects with orthogonal double axle, and has a widespread application value.
